Answer:
Prophase I
Explanation:
Meiosis is the cellular division that produces the gametes and results in 4 haploid cells. Since these cells will go on to become the offspring, it's important for genetic variation.
Crossing-over is one contribution of genetic variation because it is where the homologous chromosomes exchange parts of their genes. In meiosis, it occurs in Prophase I.

Answer:
Photoperiodism
Explanation:
The process explained in the question is called "Photoperiodism" which refers to the plants' reaction to the length of the dark and light period in a day.
When the dark period is interrupted with a certain period of artificial lighting, the plant thinks that the day had a longer period where it's "light" than it is "dark" so it gets tricked into flowering. Same concept can be applied in reverse for the plants who flower during longer periods of dark.

Answer: The cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air. The cornea is the fastest healing tissue in the human body, thus, most corneal abrasions will heal within 24-36 hours.

Parasites
Explanation:
Parasites are found on or in the body of the host and they get food by eating the host's partly digested food therefore, depriving it of nutrients which then deprives the host's ability to reproduce. This energyis diverted into parasite growth. The host's other systems are left intact, allowing it to survive and sustain the parasite.
